DOI: 10.15446/esrj.v23n3.74779
Abstract: In hard rock masses, discontinuities control the slope stability, rather than block matrix breakage. The relative position of joints and slope face defines the most likely mechanisms of failure. Among these mechanisms, the wedge failure… read more here.

DOI: 10.3390/ma15113911
Abstract: This paper presents an analytical model that quantifies the stress ratio between two test specimens for the same probability of failure based on the Weibull weakest link theory. The model takes into account the test… read more here.
